Transcranial direct current stimulation (tDCS) is associated with improved unimanual skilled hand use. The authors assessed effects of bihemispheric anodal corticomotor tDCS (BAC-tDCS) on bimanual skilled hand use. Twenty-eight nondisabled subjects were randomized to either BAC-tDCS or sham-tDCS, 20 min daily for 5 consecutive days. Performance on a bimanual typing (BT) task and a short-term memory (STM) task was assessed daily and at 1-week follow-up. Mean change between Day 1 and Day 5 in BT score with BAC-tDCS (19.4 points; 95% CI [12.82, 25.99]) was significantly greater (p =.04) than change with sham-tDCS (12.5 points; 95% CI [7.6, 17.3]). Neither group retained improvements in BT score at follow-up. BAC-tDCS had no effect on STM. These results may have implications for interventions to improve hand function in persons with bilateral hand dysfunction.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 June 2013.
All research outputs
#22,759,452
of 25,374,647 outputs
Outputs from Journal of Motor Behavior
#475
of 506 outputs
Outputs of similar age
#185,275
of 209,149 outputs
Outputs of similar age from Journal of Motor Behavior
#3
of 3 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 506 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.9. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 209,149 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 3 others from the same source and published within six weeks on either side of this one.
